This paper presents a low-power small-size LNA with a novel currentreuse circuitry for 3D ultrasound imaging systems. The proposed LNA is composed of a differential common source amplifier and a source-follower driver which share the current without using inductors. The LNA was fabricated in a 0.18-μm CMOS process with only 0.0056 mm2. The measured results show a gain of 21 dB and a bandwidth of 9 MHz. The proposed LNA achieves an average noise density of 11.3 nV/ √ Hz, and the 2nd harmonic distortion below −40 dBc with 0.1-Vpp input. The supply current is 85μA with a 1.8-V power supply, which is competitive with conventional LNAs by finer CMOS process. key words: amplifier, current-reuse, driver, ultrasound, LNA","PeriodicalId":348826,"journal":{"name":"IEICE Trans.

In this paper, event-triggered control over a sensor network is studied based on the notion of uniformly ultimate boundedness. Since sensors are located in a distributed way, we consider multiple event-triggering conditions. In uniformly ultimate boundedness, it is guaranteed that if the state reaches a certain set containing the origin, the state stays within this set. Using this notion, the occurrence of events in the neighborhood of the origin is inhibited. First, the simultaneous design problem of a controller and event- triggering conditions is formulated. Next, this problem is reduced to an LMI (linear matrix inequality) optimization problem. Finally, the proposed method is demonstrated by a numerical example.","PeriodicalId":348826,"journal":{"name":"IEICE Trans. Fundam. Electron. Commun. Comput.
